Hi Everybody, I want to measure performance in terms of units like microseconds , miliseconds etc.For my module. I'm keeping track of this by recording TSC value(64 bits). This TSC value gives me the difference in CPU cycles between the previous execution and current execution of an instance which is executing within fast interrupt Handler.And which is actually set of instructions. This is really tedious way of benchmarking. So is there any tools like IOZONE for filesystem etc? Which calculates the time difference automatically and dump that in log file. I want to recall again that my instance is executing within interrupt handler ans it is getting data for execution by means of shared FIFO with kernel thread. Please Help Thanks in advance.
